DollaTek ADS1256 24bit 8channel ADC AD Module High Precision ADC Capture Data
Overview:
ADS1256 8 street 24-bit ADC module mounted TI ADS1256IDB, minimum power consumption, high-precision ADC chips and 2.5V zero point source, with SPI interface communication protocol, data output rates up to 30ksps, support single-ended input and differential input.
Instructions:
5 V, GND: 5 V power consumption.
SCLK, DIN, DOUT, CS: SPI communication interface
DRDY: ADS1256 data are ready output (Active Low Level)
PDWN: ADS1256 Sync / Power Off (Active Low Level)
AIN0-AIN7: Analog voltage input, can be configured as 8 single-ended inputs or 4 differential inputs (the measured voltage should be shared with the module)
Interface description:
VCC, RXD, TXD, GND: UART interface
VCC, SDA, SCL, GND: I2C interface.
MISO, MOSI, SCK, CS2, CS1, CS0, GND, VCC: SPI interface
Precautions:
Since the voltage of ADS1256 is 5V and the measured voltage is 2V below the supply voltage, the module is only suitable for measuring analogue voltages within 3V.
